Description

M249253 Creation Instructions (1) I. New type of technical field This creation is about a memory card connector, especially a connector that can automatically position and eject the memory card, simplify the components, and reduce the speed of the connector. 2. In the prior art, the main body 2 is inserted into the structure 5 series component memory card at the end of the insulation card ejection machine, and bring 1, the group 2, as the work 3, the conventional notes, and the cover 2 structure 5, When a group of card ejection machines that are formed by ejecting and joining and are connected to the ejection card are installed, a plurality of air-seals are used after welding, and the operation is performed because the used ejection abuts against the turning force. The connector 1 is like the body 2. 3 is connected to the insulating case and the shielded case, among which are multiple conductive terminals 4 body 6, the mechanism 5 when the inside of the card ejection body 1 is ejected, and the mechanism 5 has the following steps: The shielding shell, its difficult card mechanism, its Lu Jiyi card, as shown in Figure 1 when the moment 'increases, including the end of the shielding shell 3, and a plurality of conductive terminals 4 and / The insulating body 2 is sword-welded to the circuit board; the withdrawal card, the connecting rod 8 and the resisting piece 9 extend a resisting arm 10, and one end of the note

The front of the sex body 6 6, the memory is set forward. The lack: many, trivial, connected to electricity. This requires a higher body. The oblique front end of the memory card pushes the front end of the card against the holding arm 10 positions. Not only increase manufacturing costs, but also waste time. When it is on the road board, it is difficult to avoid manual repair welding; when the opening is assembled to extend into the welding grab for repair welding, there is an extension-the floating resistance arm advances forward.
